WRENCH MECHANISM.

Application filed August 8,

Tool! whom it may concern:

7 Be it known thatv I, Roscon F. MORGAN, a c'it'izen of the UnitedStates of America, and a resident of Kiefer, in the county of Creek, in the State of Oklahoma, have invented eertain new and useful Improve ments in Wrench Mechanisms, whereof the following is a specification.

This invention relates to a wrench mechanism especially adapted for tightening and securing the cylinders of internal combustion engines to their engine cases.

In certain types of gas engines the inner end of the engine cylinder is secured 'to internal flanges of the outer end of the engine case by means of nuts which engage the stud bolts of the engine cylinder projecting through holes in said flanges. Access is obtained for screwing up these nuts through a hand hole in the engine case. 'In this way it .is impracticable to apply the power so as to properly tighten the parts, Y and, moreover, owing to the difficulty of operating through the hand hole, much time is Wasted. X

The objects of this invention are to shorten the time required for this wrenclr ing operation, to secure a tight jyint between the cylinder and cylinder case, and to facilitate the Work.

Figure 1 of the accompanying drawings represents a longitudinal section of the cylinder .cnd of an engine case of the type herein referred to and of a cylinder secured thereto and a side elevation of one embodiment of this wrench mechanism in operative relation for tightening said cylinder to said case.

Fig. 2 represents an end elevation of the outer end of the cylinder showing the parts of the wrenching means in connection therewith.

Fig 3 represents a transverse section of the engine case on line 3-43 of Fig. 1 looking upward and showing the parts of the, wrenching means operative at the inner endof the cylinder.

The same reference numbers indicate corresponding partsin the different figures.

In the preferred embodiment herein illustrated of this invention A represents a longitndinal section of the outer end of an onme ease of a certain type of internal com- "mstion engine and H an engine cylinder secured thereto. In engines of this type Specification of Letters Patent.

provided with the usual stud bolts 2' set in body of the cylinder and projecting through the bolt holes f of said flange. These stud bolts are provided with nuts Z which are tightened against the inner face of the flange e in securing the engine cylinder to its case. The cylinder His provided at its inner end with an intermediate head and at its outer end with-the usual stud bolts we set in the body thereof.

A wrench shaft 10, preferably constructed of steel, is provided at its imicr end with a square or other angular projection 11 and at its outer end with an angular projection 12. This shaftis IHOVldQd with an adjustable collar 15 which has a set screw 16. This collar is preferably provided with reduced steps 17 and 18 of different diametersto adapt the shaft to a stuffing box of different size in cylinders where larger pistons are enzployed.

wrench shaft support 20, preferably composed of mild steel, consists of a bar adapted to span the outer end of the cylinder. This bar is provided at its opposite adapted to engage diametrically opposite stud bolts m on said cylinder and it is provided centrally of its length with a hole 23 which serves 95 as a bearing for the wrench shaft 10.

A wrench 30 for tightening the stud nuts for securing the cylinder to the case consists of a thin straight offset arm preferably .composed of vanadium steel drop forged 1 o0 one end with a wrench angular socket 41 which engages the angular 105 projection 11 at the inner end of the wrench shaft 10, This crank is provided at its outer end with a stud 42 preferably carr ing a grooved antifriction' roller 43, which,

preferably composed of case hardened steel, no

' crank so contacts with said Wrench 31. A. set screw 44, preferably composed of tempered steel fastens the driving crank to said shaft.

An actuating wrench 50, preferably a drop forging. is provided with an angular socket 51 which {its the angular projection 12 of the i'rcnch shaft 10. This driven manually or otherwise Operates this Wrench mechanism.

In the useof this wrenching vgpuretus, i first measure the length of the stuiiing boi and then adjust and fasten by means of the said screw l6the roller 15 on the wrench. sue-ft 10 at a point which will permit said collar to serve as 0. stop against the inner end of said shilling box, with the end of said shaft in its full diameter flush or nearly so with the outer end of said striding box and the angular extension 11 projecting beyond the said box. Then the shaft 10 is passed into the cylinder end its inner per- 'tion projected through the stuiiing box 5,

the collar 15 engaging the outer end thereoit. Then the shaft supportis placed on the shaft 10 and secured to opposite stud. bolts m at the outer end of the cylinder. 'llhen. the driving crank 40 is passed through the hand hole g and placed on the extension 11 st the inner end of said shaft end secured- .thereto by the set screw ll. The huh if this driving crank engages the outer oi the stuffing box and in conjunction. the collar 15 prevents endwise I.-91'IQ the shaft 10. .The Wrench idis Q through the hand hole 9, epplie-zl the nuts to be tightened end edjiistci inclined position to "ard the left" in ment with the antifriction roiier 43 as shown in full lines in i i The. actuating wrench 50 then applied by sociret 51 to the outer angular extension 12 oil the Wrench shaft 10. Then the ectusting Wrench 50 is moved it half torn and the'driving crank i0 is thereby swung to Ward the right carrying ii'itli it the wrench 30 and putting the parts" in position indiceted in dotted lines in 52. 'ilhcn, necessary to complete the tighte ing" the parts are readjusted to normal )()H1Ll( l to: the beginning of the wrench stroke mid 2111 other turn given the nut; the one men be ing; repented us many times as necessary.

I have herein described the preferred eniloocliinent of my invention but changes may be made therein Without a departure from the spirit or scope of the invention.
